Title: Improvements in and relating to cylinder locks
Inventor: STANTON WILLIAM HENRY
IPC: E05B29/04
Filed: 1963-02-21
Abstract: 1,030,921. Locks. CHUBB & SONS LOCK & SAFE CO. Ltd. Feb. 20, 1964 [Feb. 21, 1963], No. 7018/63. Heading E2A. A lock comprises a cylindrical magazine 10 rotatably mounted in a casing 18, the magazine housing a stack of plates each adapted to be displaced radially of the magazine, between positions in which, respectively, the plate extremities do, and do not, project beyond the periphery of the magazine, under the action of a key insertable into a tunnel formed by apertures 16 in the stacked plates, wherein the stack comprises plates of two or more kinds which differ from one another as regards one or more of the location, size and shape of the key aperture and each plate is moved by the sliding action of its respective key section against the edge of its aperture as a result of turning the key. The hollow cylinder 10 has longitudinal slots 11 along opposite sides and terminates in a flat sided shank 12. Parallel edges 15 on the plates slide against the inner flat surfaces 14 of the cylinder 10, the respective dimensions of the surfaces 14, 15 being of such a size as to allow movement of the plates to one of the extreme positions, i.e. with the plates extending beyond the periphery of the magazine. The key has profiled sections each corresponding to the aperture of the plate with which it co-operates. The key profile is of such a shape that on rotating the key the plate moves radially of the magazine and on a reverse rotation the plate returns to its former position. In one embodiment the plates are of equal length but the aperture is in different positions, similar positions being given the same references, i.e. 1, 3, 5, 7 or 9, e.g. for a plate having a central aperture the numeral reference is 5-5. The aperture shape may be varied provided the corresponding key profile actuates the plate. The size of the aperture may also be varied. The housing 18 has slotted recesses 19 into which the plates are displaced by rotation of the key, preventing rotation of the magazine. On rotation of the key in the unlocking sense the plates are withdrawn into the magazine leaving it free to rotate in the housing 18 to effect movement of e.g. a bolt or door latch. To prevent or increase the difficulty of opening the lock by manipulation or other tampering the plates may be formed with notches 20 which in the locked position extend into recesses 19 and which are in alignment with ribs 21 so that if rotation of the plates is forced the notches move into engagement with the ribs 21 and prevent unlocking. The plates may also be cut away as shown at 20, 25 in Fig. 2c (not shown). The trailing edge of the plate may be formed with saw-teeth 23 (Fig. 2d, not shown) which engage with a lip 24 if an attempt is made to force the lock.

Title: Improvements in or relating to valves for controlling and/or regulating the flow of fluid
IPC: F24H9/20
Filed: 1931-03-09
Abstract: 380,454. Fluid flow regulators. GAS LIGHT & COKE CO., CLARK, J. G., and MASTERMAN, C. A., 84, Horseferry Road, London. March 9, 1931, No. 7255. [Class 135.] In a combined gas regulator and waterdeficiency safety device for use with geysers &c., the suction produced by an ejector nozzle 31 when water is being supplied to the geyser 39 by the pipe 38 causes a reduced pressure to be transmitted by a branch pipe 36 to the space beneath the lower of two superposed diaphragms 1, 2, thus causing the said diaphragm to bulge downwardly and allowing a gas valve 15 to open. When the water is turned off, the suction at the ejector nozzle ceases and the head of water in the pipe 36 pressing the diaphragm 2 upwardly maintains the valve 15 closed. The valve 15 is shaped at 21 to rest on a block 14. The diaphragm 2 is clamped between this block 14 and a fluidtight washer 13. The spindle 20 of the valve 15 is threaded to receive weights 18, 19 between which the upper diaphragm 1 is clamped. The diaphragm 1 and the valve 15 constitute an ordinary diaphragm pressure regulator and, when the block 14 is lowered, regulate the passage of gas through an opening 7 connecting the gas inlet 4 of the casing 3 with the gas outlet 5. Annuli 8, 25 close the ends of the casing 3 and clamp the peripheral parts of the diaphragms 1, 2. A perforated plate 12 limits the downward movement of the lower diaphragm. A pipe 28 leading to a pilot jet is permanently in communication with the inlet 4 by means of bores 23, 24 in the valve. The water supply pipe 38 is constricted at 33. In a modification, the pipe 28 and bores 23, 24 are omitted and the space above the diaphragm 1 is in communication with the atmosphere by an air-venting passage, a recess above which may be closed by a screw plug if the upper diaphragm is ruptured. In this form, the annulus 25 is provided with a closing cap and the valve 15 is flat-bottomed so as to rest on a metal-faced rubber block fixed to the diaphragm 2. Two inlets are provided, so that either can be used according as the valve is right-handed or left-handed.

Patent GB-560632-A (GB)
Title: Manufacture of lactones of the cyclopentanopolyhydrophenanthrene series
IPC: C07J9/00
Filed: 1942-05-29
Abstract: Lactones of the cyclopentanopolyhydrophenanthrene series are prepared by the action of a halogen fatty acid on a compound of the general formula R-A-CO-CHY-R1 where R is a cyclopentanophenanthrene nucleus which may, if desired, carry substituents, A is a branched or unbranched aliphatic hydrocarbon residue, Y is hydrogen or alkyl and R1 is a free or substituted hydroxyl group.  The products of the invention may, if desired, be hydrolyzed and re-esterified.  In examples: (1) 3 : 7 : 12-triacetoxy-norcholanyl-(23)-acetoxymethylketone is treated with bromacetic ester in benzene solution in the presence of zinc.  The product is acetylated to form D a  : b  - b  - [3 : 7 : 12 - triacetoxy - norchoanyl - (23)] - butenolid.  (2) D 5 : 6 - 3 - acetoxy - 25 - diazo - 26 : 27 - bisnor - cholestene - 24 - one is boiled with acetic acid to form D 5 : 6 - 3 : 25 - diacetoxy - 26 : 27 - bisnor - cholestene - 24 - one which is treated with bromacetic ester in benzene solution in the presence of zinc.  The lactonisation is completed by treatment with concentrated hydrochloric acid to form b -[D 5 : 6 - 3 - oxy - norcholenyl - (23)] - b  : g  - dioxy - n butyric acid - g  - lactone.  Acetylation with acetic anhydride gives b -[D 5 : 6 - 3 - acetoxy - norcholenyl - (23)] - butenolid.  If instead of bromacetic ester the corresponding propionic ester is used there is formed the corresponding butenolid methylated in the a -position.  By starting with the corresponding nor-cholestene instead of the bisnor-compound there is obtained a final product containing a methyl group in the g -position.  (3) D 5 : 6 - 3 - oxy - 17 - [173 - acetoxy - 172 - oxopropyl, androstene is treated with bromacetic ester in benzene solution in the presence of zinc-copper alloy to give D a :b  - b  - [D 5 : 6 - 3 - acetoxy - 21 - norpregnenyl-(20)]-butenolid, which may, if desired, be saponified. Alternative parent materials which may be used and which result in the same final product are the corresponding 173-oxy-, and 173-alkoxy-compounds.
